What are the best online casinos for USA players?

From our experience and player feedback, these are the current top 3 US online casinos:

1. Las Atlantis
2. BetUS
3. El Royale Casino

Is it safe to play at US online casinos?

Can I play casino games for free?

Yes, you can play casino games for free. Many sites allow “demo” or “practice” gameplay after you create an account. It lets you try out new games before you invest your money. Some gambling sites even have no deposit offers to give you a small amount of cash to wager. You will not win any real cash while playing for free.

How do I determine which online casino is the best?

Your playing preferences often determine the best site for you. Some sites offer specific games and attractive bonuses, while others appeal to the general player.

The best place to start your search is the OUSC reviews. We include specific categories to help you determine which is the top US online casino for you.

What types of games can I play?

You’ll find almost any title you can imagine at US online casinos. Most sites offer slots, video poker, blackjack, roulette, and specialties like scratch cards, keno, and bingo.

What kind of bonuses will I receive?

New players typically receive a welcome or deposit bonus. A deposit bonus is usually matched 100% but can go as high as 400%. After that, you can expect a wide range of player promotions, tournaments, and other ongoing offers.

Be sure to research the terms and conditions before you play. Check our guide to online casino bonuses for everything you need to know.

Does a 3rd party audit all online casinos?

Most online casinos use respected verification companies, which help to regulate the industry. If a site has the seal of approval from one of these groups, like eCOGRA, that proves legitimacy and trustworthiness. Legitimate establishments also hire third-party auditors to test the security and fairness of a site’s operations. Gaming Associates, iTech Labs, and Technical Systems Testing (TST) are three leading auditors.
